GFN-262144 Mega Prime!

PrimeGrid - Po, 20.11.2017 - 13:38
On 16 November 2017, 15:38:45 UTC, PrimeGrid’s Generalized Fermat Prime Search found the Generalized Fermat mega prime: 3596074^262144+1 The prime is 1,718,572 digits long and enters Chris Caldwell's The Largest Known Primes Database ranked 6th for Generalized Fermat primes and 53rd overall. The discovery was made by Howard Gordon ([PST]Howard) of the United Kingdom using a Nvidia GeForce GTX 1060 in an AMD Ryzen 1950X with 32GB RAM, running Microsoft Windows 10 Core Edition. This GPU took about 30 minutes to probable prime (PRP) test with GeneferOCL3. Howard is a member of the PrimeSearchTeam team. Double-checker information will be provided once available. The PRP was confirmed prime by an Intel(R) Core(TM) i5-4670K CPU @ 3.40GHz with 24GB RAM, running Microsoft Windows 7 Professional Edition. This computer took about 10 hours 10 minutes to complete the primality test using multithreaded LLR. For more details, please see the official announcement.

Pierre de Fermat's Birthday Challenge in 12 hours!

PrimeGrid - Pi, 17.11.2017 - 02:39
In less than 12 hours, PrimeGrid's three day Pierre de Fermat's Birthday Challenge will begin. For the first time ever, this challenge will feature the three smallest Generalized Fermat projects, GFN-15, GFN-16, and GFN-17-Low. Head on over to the the challenge's forum thread for more information and discussion. Good luck!

Online questionnaire about citizen science and volunteer computing

Einstein@Home - St, 15.11.2017 - 09:27

Please help Lo Lee, a first-year doctoral student from Library and Information Science at University of Illinois at Urbana-Champaign, by filling in an online survey about Einstein@Home and BOINC. Lo Lee is doing a project on citizen science that aims to assess to what extent citizen science can be designed as an inclusive online learning environment to embrace volunteer diversity.

Announcing: Fewer Announcements!

PrimeGrid - Ut, 14.11.2017 - 15:38
In 2018, we are changing our policies regarding announcement of significant prime discoveries. We're raising the bar so that announcements once again are something special and not just "the prime of the week." Details and discussion can be found here.

Another PPS-Mega Prime!

PrimeGrid - Ut, 14.11.2017 - 13:24
On 13 November 2017, 00:26:44 UTC, PrimeGrid’s PPS Mega Prime Search project found the Mega Prime: 943*2^3442990+1 The prime is 1,036,447 digits long and will enter Chris Caldwell's The Largest Known Primes Database ranked 208th overall. The discovery was made by Joshua Charles Campbell (Warp Zero) of Canada using an Intel(R) Core(TM) i7-7700K CPU @ 4.20GHz with 64GB RAM, running Linux. This computer took about 42 minutes to complete the primality test using multithreaded LLR. Joshua is a member of the Canada team. The prime was verified on 13 November 2017, 18:22:32 UTC by Jon Goral ([KWSN]John Galt 007) of the United States using an Intel(R) Core(TM) i7 940 CPU @ 2.93GHz with 24GB RAM, running Microsoft Windows 10. This computer took about 6 hour 76 minutes to complete the primality test using LLR. Jon is a member of The Knights Who Say Ni! team. For more details, please see the official announcement.

Database slowness

SETI@Home - So, 11.11.2017 - 02:09
We're having some as yet unexplained slowness with the our BOINC database. There don't seem to be any hardware issues. Temperatures are running normal and all the drives seem good. Yet for some reason the query that fills the "ready to send" queue is running about 10 times slower than it normally does.

Until I get it fixed, it means that on average we're sending out 3 workunits a second rather than 30+.

I'll let you know when I've got it figured out.

New multicore app and WUs

GPUGRID - Pi, 10.11.2017 - 16:58
Dears, we would like to test our new CPU multicore application for quantum chemistry tasks ("QC"). Since it’s the first time we have a CPU app out, I’ll test the behavior of GPUGRID with a relatively large batch that you will see soon. Workunits are named "*QC309big*". Here’s some features of the app, in short (subject to change): * Platform: Linux only for now, generic x64. * Threads: as many as Boinc decides. I guess it depends on your machine, your preferences, and other running tasks in ways which are obscure to me… * Run time: about 1 CPU hour per WU (so, shorter if multithreading) * Credit: computed with the default algorithm (tasks are short, don’t expect much). Bonus mechanism for fast turnaround is still on. * Known bugs: restarts and checkpoints. This should be mitigated with the “keep in memory when suspended” option. Sorry about that, it’s outside of our control. * Network behavior: the first time you get a WU of this kind it downloads a Python interpreter (miniconda) and then some open-source packages, and installs them in the project directory. The installation is reused whenever possible. * Disk usage: could go around 1 GB, perhaps more when tasks are running. Resetting the project should remove everything. * Memory usage: should be around 1 GB when running. Depending on the results of this test, we’ll start thinking about other platforms. Thanks and nice crunching! Toni

Perfect Cuboid: Starting skipped range with more cuboids

yoyo@home - Pi, 10.11.2017 - 01:00
In the Perfect Cuboid subproject we have added per user statistics of found cuboids, as well as subproject status page was extended by the common statistics. 11 November at 11:11 UTC we are going to launch the 0-10T range which we skipped from the beginning, which contains almost the same amount of cuboids we've already discovered, and throw out 4 times shorter tasks to give an opportunity for all concerned users to put into the personal statistics a large number of cuboids. So, don't miss the start time.
